MPI Tutorial Shao-Ching Huang IDRE High Performance Computing Workshop 2013-02-13The Intel MPI Library is available as a standalone product and as part of the Intel® oneAPI HPC Toolkit.The Intel MPI Library is a multi-fabric message passing library that implements the Message Passing Interface, version 3.1 (MPI-3.1) specification. Use the library to develop applications that can run on multiple cluster interconnects.Communicators and Ranks. Our first MPI for python example will simply import MPI from the mpi4py package, create a communicator and get the rank of each process: from mpi4py import MPI comm = MPI.COMM_WORLD rank = comm.Get_rank() print('My rank is ',rank) Save this to a file call comm.py and then run it: mpirun -n 4 python comm.py.Using MPI with Fortran. Parallel programs enable users to fully utilize the multi-node structure of supercomputing clusters. Message Passing Interface (MPI) is a standard used to allow different nodes on a cluster to communicate with each other.
